My read of this is that she's just testing you, and mayby subconsciously trying to put you through some of the turmoil she went through.
No its not constructive, but WS's aren't known for being constructive... they basically put the work in your lap and they go off to brood.
I think you need to read the subtext rather than focus on the threat... what i am hearing is that she's still scared, still doesnt' trust you, and is still hurt.
THAT is understandable. MWD said in her DR book that a ROUGH estimate of D-busting time is one month for every YEAR you were together.. so you may have to deal with up to ten months of this... are you up for it?
